GRAlN -CAR DQOR.

SPECIFICATION forming part of Letters Patent No. 738,791, dated September 15, 1903.

Application filed January 12,1903. Serial No. 138,727. (No model.)

To otZZ whom it may concern:

Be it known that I, EDWARD J. GESKE, a citizen of the United States, residing at Wykoff, in the county of Fillmore and State of Minnesota, have invented a new and useful Grain- Oar Door, of which the following is a speoification.

My invention relates to doors for graincars; and its object is to provide a door which is of strong construction adapted to withstand the strain imposed by heavy loads of grain, which can be securely closed without nailing, Which can be readily opened, and which can be readily removed from its frame when desired. In attaining these endsI make use of the construction hereinafter fully described and claimed, and shown in the accompanying drawings.

Figure 1 is a front elevation from without of a door-frame with a car-door constructed after myinvention mounted thereon, the door being shown in solid lines as closed and locked and in dotted lines as opened to its fulleX- tent. Fig. 2 is a detail view showing the mode of disconnecting the door from the frame.

Referring to the drawings, 1 represents the bottom, and 3 and t the sides, of a door-frame.

5 is the car-door, provided with a cleat or rib 6, extending vertically across the middle of the door on the outer surface.

7 and 8 are two members of the truss-rod, connected by a turnbuckle 9, which extends transversely across the front of the door near the top, forming, together with a similar trussrod near the bottom of the door and the rib previously mentioned, means to prevent the bulging of the door under the weight of a load of grain behind it.

10 10 are two crankshafts, each consisting of a body portion 11, passing through the eyes 12 and 13, the end portion 14, journaled in a socket 15 on the door-frame, and a lever portion 16, by means of which the crank-shaft is revolved in its journals and the door opened andclosed. Theleverportion16isflattenedat its end and provided with aslot 17,with which a projection 18 near the top of the door engages. The projection 18 is transversely pierced by a series of openings 19, 20, and 21, through which the latch member 22, suspended by a chain or other suitable means 23, is adapted to engage to lock the lever end of the crankshaft in position, and so close the grain-door securely. Slightly above the eyes 12 and 13 and somewhat nearer the middle vertical line of the door are secured two lugs or keepers 24 2 1, which serve to prevent any longitudinal movement of the crank-shaft 10 in the eyes 12 and 13 when the lever ends are turned upward to lock the door in closed position.

The relation of the various parts of my invention when the door is in closed position is apparent from the inspection of Fig. 1.

'When it is desired to release the door, the

latches 22 22 are withdrawn from engagement with the projections 18 and the levers 10 of the crank-shafts are drawn downward. This movement causes the rotation of the body portion 11 of the crank-shaft in the eyes 12 and 13 and a rotation of the end portions 14 in the sockets in the door, with aconsequent lifting of the door upward to a distance sufficient to allow the free escape of the grain from the car. The position of the parts after the door is completely raised will be appar ent from inspection of Fig. 2.

If it is desired to detach the door completely from the frame, all that is necessary is to move the crank-shafts toward the middle of the door by sliding them in the eyes 12 and 13 when the door is in the raised position. This movement, which will be readily understood from inspection of Fig. 2, causes the withdrawal of the end portions 14: of the crank-shaft from their sockets 15 in the doorframe.

When the door is closed and the lever ends of the crank-shafts latched to the projections 18 at the top of the door, the lugs or keepers 2,4 effectively prevent any slipping of the crank-shafts in the eyes 12 and 13, as already explained.

Having now fully described and shown my improved grain-car door, what I regard as new, and desire to secure by Letters Patent, IS-w.

1. In combination, a door-frame, a graindoor, journals in said frame and on said door, a door-hanger comprising a pair of horizontal crank-shafts rotatably and slidably mounted in the journals on said door, each of said crank-shafts having one end removably j our-= aled in one of the journals in said door-frame,

and means for turning said crank-shafts in said journals to open and close said door.

2. In combination, a door-frame, a graindoor, journals in said frame and on said door, and a door-hanger comprising a pair of horizontal crank-shafts rotatably and slidably mounted in the journals on said door, each of said shafts having one end removably journaled in one of the journals in the doorframe and having the other end bent at right angles to the remainder of the shaft to form an operating lever adapted to rotate the crank-shaft in its journals and to engage with suitable fastening means to lock the door when closed.

3. In combination, a door-frame, a graindoor, journals in said frame and on said door,

a pair of horizontal crank-shafts rotatably and slidably mounted in the journals on said door, eaoh crank-shaft having" one end removably journaled in one of the journals on said door-frame and the other bent to form an operating-lever, and a pair of lugs fixed upon said door adjacent to the lever ends of said crank-shafts and adapted to prevent sliding movement of said crank-shafts in their journals when the door is closed.

In testimony that I claim the foregoing as my own I have hereto affixed my signature in the presence of two witnesses.

EDWARD J. GESKE.
